The whole point is to be able to power to drive of a clean LPS instead of the motherboard. The difference between MB and LPS is clearly audible and provides an audible positive improvement when using a decent linear power supply. It’s very easily to test as well. Flip the dip switch between internal MB and external LPS and let your ears decide which sounds better. It does not matter at all how dirty the power coming to the SSD is, as long as it is within specs, so the SSD can work reliably. Choice of drive has generally no impact on sound, as long as it can deliver audio before the decoding buffer runs empty, and does not alter the files (drive failures, dead sectors, bit flips). The entire digital audio chain up to the DAC is completely deterministic, as it should be; the hardware used does not matter, as long as it works reliably. This drive will make zero difference to the raw digital audio sent to your DAC, bit-identical. Now, what about the analog audio signal created by the DAC, can that be influenced by choice of SSD? If DAC and SSD share the same power source, theoretically yes. If not, no. Also, dirty power can be cleaned, that's what those big capacitors on expensive amps and sound cards are for. And direct acoustic noise? I have never heard the noise of an SSD, but that might be because I haven't yet put my ears inches away from a working SSD. The vast majority of SSDs are probably quieter than other parts of your computer, and probably below the noise floor of your room and your own ears anyway, at a normal distance. My conclusion: Unless your previous drive was particularly noisy, any perceived auditory differences between this SSD and your previous drive are completely imaginary. That is especially true for switching between MB power and dedicated power supply for this SSD, which, in case of using a dedicated DAC with dedicated power supply, can not even make a difference in theory. You and many others in this thread have fallen victim to the placebo effect. MarcelNL, ASRMichael, acbarn and 9 others 4 1 4 3 Link to comment

Say, power such card with external linear power supply that measures objectively better (less noise) than a common motherboard USB output, concluding no difference, just placebo? Oh no, that is a very different case, as I think I have already explained. It is always a good idea to power the DAC with a separate high quality power supply to make sure other devices sharing the same power supply don't produce electric noise strong enough to not be cleaned sufficiently and cause audible noise in your DAC's analog output. If you already use a DAC powered by its own power supply, reducing electric noise in components sharing another power supply won't make a difference.

Or add a stretch of fiberoptics in the network of which you stream? Tinker with latency settings in your OS? The theory that 0s and 1s are just that and nothing matters is something that keeps the engineers happy, ears tell a different tale. Find a good pair of speakers capable of great resolution and a decent amp without too many frills and try, you'll be amazed how many things have an effect on how the 0s and 1s flowing into your DAC and what differences come out of it. No, just no. It is absolutely impossible for any of those things to make any difference to the DAC output, aside from latency, which does not matter for music listening unless you want a more responsive play/pause button. Pure placebo. beautiful music, Spacecase, MarcelNL and 8 others 2 5 4 Link to comment

The difference between a consumer and an audiophile is that we test the limits vs trust pundits. People listen to music, not machines. I don't think any of the people here making these hard-to-believe claims have conducted proper double-blind tests, that would be the only way to give those claims some validity. When noone can properly explain an effect, there should better be some good evidence that it exists at all, before you believe in it. Iving, Exocer, beautiful music and 5 others 2 3 3 Link to comment
